Introduction to Natural Polymers: From Sugars to DNA

The video discusses naturally occurring polymers found in living organisms, such as wood, proteins, and DNA. It explains how these polymers are made from monomers through condensation reactions. Wood is composed of sugar molecules, forming polysaccharides like cellulose and starch. Proteins are polymers of amino acids, while DNA is a polymer of nucleotides, forming a double helix structure that encodes genetic information.
